BU4922G-TR Overview
A total of 5 terminals are used to mount this power management. Power management is packaged in a Tape & Reel (TR) way. Power management is possible to find a series of 1 functions. There are 1 channels on this power managment ic that can be found in a series. IC management is packaged as a SC-74A, SOT-753 package. Several of the benefits of this PMIC are also shared by other Simple Reset/Power-On Reset products. In a 2.4V supply voltage, the power management conducts. In a 1 supply voltage, the PMIC chip conducts. By Surface Mount, IC management has been mounted. This power ic can be sub-categorized as Power Management Circuits. The total number of pins on this power management is 5. 5 pins are present on the power management system. It is recommended that Vsup should not be less than 700mV for this IC power. During this IC power, the maximum supply voltage (Vsup) should not exceed 7V volts. Power management recommends the Surface Mount mounting type. This power management is the recommended temperature range for the supervisors: -40°C~125°C TA. While this power management is operating, it will output Push-Pull, Totem Pole as the output voltage. There is a 550nA supply current present in the power management. For similar manage ics search of the manufacturer, you can always refer to BU49*, the base PMIC number. The maximum supply temperature that PMIC chip can work with is 1.23μA.
